  • Patent number: 9179106
    Abstract: A measurement system includes an illumination unit, imaging unit, acquisition unit and correction unit. A measurement target is irradiated with illumination light. The imaging unit captures an image of light reflected by or transmitted through the measurement target. The acquisition unit acquires positional relationship information representing a positional relationship between the illumination unit and the measurement target and between the imaging unit and the measurement target. The correction unit corrects a luminance of at least one of the illumination light emitted by the illumination unit and the captured image based on the positional relationship information in such a way as to correct a luminance change of the measurement target image, wherein at least two of the measurement target, the illumination unit, and the imaging unit are variable in spatial position.

  • Patent number: 9088729
    Abstract: An imaging apparatus images an imaging target region by dividing the imaging target region into a plurality of divided regions and generates a merged image of a larger region than the divided regions by merging the obtained images of the respective divided regions. A method of the imaging apparatus includes acquiring a first image and a second image in each of the plurality of divided regions, performing image alignment between adjacent divided regions using the second images, and generating the merged image by merging the first images of the adjacent divided regions based on a result of the alignment performed using the second images.

  • Publication number: 20140333751
    Abstract: An image processing apparatus includes an image data acquisition unit, a display control unit, an area-information acquisition unit, and a detection unit. The image data acquisition unit acquires Z-stack image data including multiple layer images obtained by using a microscope apparatus. The display control unit displays at least one of the layer images on a display apparatus as an observation image. The area-information acquisition unit acquires information about a target area in the observation image specified by a user. The detection unit detects in-focus information for a corresponding area for the target area in each of the layer images. The display control unit displays an image indicating a positional relationship between the target area and the corresponding area which is closer to an in-focus state than the target area, along with the target area on the display apparatus, based on the result from the detection unit.

  • Patent number: 8885027
    Abstract: For example, display image input units 131R, 131L detect additional information indicating left and right directionality from images for display. Then, in a stereoscopic display device having a display device for the right eye and a display device for the left eye, a switcher 132 capable of switching the connections between input and output input-output is controlled so that the correct image for display is provided to the correct display device. With such a configuration, even when the cables are connected incorrectly, it is still possible to input stereoscopic images to the stereoscopic display device so that such images are always displayed in the correct left-right relation.
